<FONT color="green">067</FONT>    /**<a name="line.67"></a>
<FONT color="green">068</FONT>     * &lt;p&gt;A specialized hierarchical configuration class that is able to parse XML<a name="line.68"></a>
<FONT color="green">069</FONT>     * documents.&lt;/p&gt;<a name="line.69"></a>
<FONT color="green">070</FONT>     *<a name="line.70"></a>
<FONT color="green">071</FONT>     * &lt;p&gt;The parsed document will be stored keeping its structure. The class also<a name="line.71"></a>
<FONT color="green">072</FONT>     * tries to preserve as much information from the loaded XML document as<a name="line.72"></a>
<FONT color="green">073</FONT>     * possible, including comments and processing instructions. These will be<a name="line.73"></a>
<FONT color="green">074</FONT>     * contained in documents created by the {@code save()} methods, too.&lt;/p&gt;<a name="line.74"></a>
<FONT color="green">075</FONT>     *<a name="line.75"></a>
<FONT color="green">076</FONT>     * &lt;p&gt;Like other file based configuration classes this class maintains the name<a name="line.76"></a>
<FONT color="green">077</FONT>     * and path to the loaded configuration file. These properties can be altered<a name="line.77"></a>
<FONT color="green">078</FONT>     * using several setter methods, but they are not modified by {@code save()}<a name="line.78"></a>
<FONT color="green">079</FONT>     * and {@code load()} methods. If XML documents contain relative paths to<a name="line.79"></a>
<FONT color="green">080</FONT>     * other documents (e.g. to a DTD), these references are resolved based on the<a name="line.80"></a>
<FONT color="green">081</FONT>     * path set for this configuration.&lt;/p&gt;<a name="line.81"></a>
<FONT color="green">082</FONT>     *<a name="line.82"></a>
<FONT color="green">083</FONT>     * &lt;p&gt;By inheriting from {@link AbstractConfiguration} this class<a name="line.83"></a>
<FONT color="green">084</FONT>     * provides some extended functionality, e.g. interpolation of property values.<a name="line.84"></a>
<FONT color="green">085</FONT>     * Like in {@link PropertiesConfiguration} property values can<a name="line.85"></a>
<FONT color="green">086</FONT>     * contain delimiter characters (the comma ',' per default) and are then split<a name="line.86"></a>
<FONT color="green">087</FONT>     * into multiple values. This works for XML attributes and text content of<a name="line.87"></a>
<FONT color="green">088</FONT>     * elements as well. The delimiter can be escaped by a backslash. As an example<a name="line.88"></a>
<FONT color="green">089</FONT>     * consider the following XML fragment:&lt;/p&gt;<a name="line.89"></a>
<FONT color="green">090</FONT>     *<a name="line.90"></a>
<FONT color="green">091</FONT>     * &lt;p&gt;<a name="line.91"></a>
<FONT color="green">092</FONT>     * &lt;pre&gt;<a name="line.92"></a>
<FONT color="green">093</FONT>     * &amp;lt;config&amp;gt;<a name="line.93"></a>
<FONT color="green">094</FONT>     *   &amp;lt;array&amp;gt;10,20,30,40&amp;lt;/array&amp;gt;<a name="line.94"></a>
<FONT color="green">095</FONT>     *   &amp;lt;scalar&amp;gt;3\,1415&amp;lt;/scalar&amp;gt;<a name="line.95"></a>
<FONT color="green">096</FONT>     *   &amp;lt;cite text="To be or not to be\, this is the question!"/&amp;gt;<a name="line.96"></a>
<FONT color="green">097</FONT>     * &amp;lt;/config&amp;gt;<a name="line.97"></a>
<FONT color="green">098</FONT>     * &lt;/pre&gt;<a name="line.98"></a>
<FONT color="green">099</FONT>     * &lt;/p&gt;<a name="line.99"></a>
<FONT color="green">100</FONT>     * &lt;p&gt;Here the content of the {@code array} element will be split at<a name="line.100"></a>
<FONT color="green">101</FONT>     * the commas, so the {@code array} key will be assigned 4 values. In the<a name="line.101"></a>
<FONT color="green">102</FONT>     * {@code scalar} property and the {@code text} attribute of the<a name="line.102"></a>
<FONT color="green">103</FONT>     * {@code cite} element the comma is escaped, so that no splitting is<a name="line.103"></a>
<FONT color="green">104</FONT>     * performed.&lt;/p&gt;<a name="line.104"></a>
<FONT color="green">105</FONT>     *<a name="line.105"></a>
<FONT color="green">106</FONT>     * &lt;p&gt;The configuration API allows setting multiple values for a single attribute,<a name="line.106"></a>
<FONT color="green">107</FONT>     * e.g. something like the following is legal (assuming that the default<a name="line.107"></a>
<FONT color="green">108</FONT>     * expression engine is used):<a name="line.108"></a>
<FONT color="green">109</FONT>     * &lt;pre&gt;<a name="line.109"></a>
<FONT color="green">110</FONT>     * XMLConfiguration config = new XMLConfiguration();<a name="line.110"></a>
<FONT color="green">111</FONT>     * config.addProperty("test.dir[@name]", "C:\\Temp\\");<a name="line.111"></a>
<FONT color="green">112</FONT>     * config.addProperty("test.dir[@name]", "D:\\Data\\");<a name="line.112"></a>
<FONT color="green">113</FONT>     * &lt;/pre&gt;&lt;/p&gt;<a name="line.113"></a>
<FONT color="green">114</FONT>     *<a name="line.114"></a>
<FONT color="green">115</FONT>     * &lt;p&gt;Because in XML such a constellation is not directly supported (an attribute<a name="line.115"></a>
<FONT color="green">116</FONT>     * can appear only once for a single element), the values are concatenated to a<a name="line.116"></a>
<FONT color="green">117</FONT>     * single value. If delimiter parsing is enabled (refer to the<a name="line.117"></a>
<FONT color="green">118</FONT>     * {@link #setDelimiterParsingDisabled(boolean)} method), the<a name="line.118"></a>
<FONT color="green">119</FONT>     * current list delimiter character will be used as separator. Otherwise the<a name="line.119"></a>
<FONT color="green">120</FONT>     * pipe symbol ("|") will be used for this purpose. No matter which character is<a name="line.120"></a>
<FONT color="green">121</FONT>     * used as delimiter, it can always be escaped with a backslash. A backslash<a name="line.121"></a>
<FONT color="green">122</FONT>     * itself can also be escaped with another backslash. Consider the following<a name="line.122"></a>
<FONT color="green">123</FONT>     * example fragment from a configuration file:<a name="line.123"></a>
<FONT color="green">124</FONT>     * &lt;pre&gt;<a name="line.124"></a>
<FONT color="green">125</FONT>     * &amp;lt;directories names="C:\Temp\\|D:\Data\"/&amp;gt;<a name="line.125"></a>
<FONT color="green">126</FONT>     * &lt;/pre&gt;<a name="line.126"></a>
<FONT color="green">127</FONT>     * Here the backslash after Temp is escaped. This is necessary because it<a name="line.127"></a>
<FONT color="green">128</FONT>     * would escape the list delimiter (the pipe symbol assuming that list delimiter<a name="line.128"></a>
<FONT color="green">129</FONT>     * parsing is disabled) otherwise. So this attribute would have two values.&lt;/p&gt;<a name="line.129"></a>
<FONT color="green">130</FONT>     *<a name="line.130"></a>
<FONT color="green">131</FONT>     * &lt;p&gt;Note: You should ensure that the &lt;em&gt;delimiter parsing disabled&lt;/em&gt;<a name="line.131"></a>
<FONT color="green">132</FONT>     * property is always consistent when you load and save a configuration file.<a name="line.132"></a>
<FONT color="green">133</FONT>     * Otherwise the values of properties can become corrupted.&lt;/p&gt;<a name="line.133"></a>
<FONT color="green">134</FONT>     *<a name="line.134"></a>
<FONT color="green">135</FONT>     * &lt;p&gt;Whitespace in the content of XML documents is trimmed per default. In most<a name="line.135"></a>
<FONT color="green">136</FONT>     * cases this is desired. However, sometimes whitespace is indeed important and<a name="line.136"></a>
<FONT color="green">137</FONT>     * should be treated as part of the value of a property as in the following<a name="line.137"></a>
<FONT color="green">138</FONT>     * example:<a name="line.138"></a>
<FONT color="green">139</FONT>     * &lt;pre&gt;<a name="line.139"></a>
<FONT color="green">140</FONT>     *   &amp;lt;indent&amp;gt;    &amp;lt;/indent&amp;gt;<a name="line.140"></a>
<FONT color="green">141</FONT>     * &lt;/pre&gt;&lt;/p&gt;<a name="line.141"></a>
<FONT color="green">142</FONT>     *<a name="line.142"></a>
<FONT color="green">143</FONT>     * &lt;p&gt;Per default the spaces in the {@code indent} element will be trimmed<a name="line.143"></a>
<FONT color="green">144</FONT>     * resulting in an empty element. To tell {@code XMLConfiguration} that<a name="line.144"></a>
<FONT color="green">145</FONT>     * spaces are relevant the {@code xml:space} attribute can be used, which is<a name="line.145"></a>
<FONT color="green">146</FONT>     * defined in the &lt;a href="http://www.w3.org/TR/REC-xml/#sec-white-space"&gt;XML<a name="line.146"></a>
<FONT color="green">147</FONT>     * specification&lt;/a&gt;. This will look as follows:<a name="line.147"></a>
<FONT color="green">148</FONT>     * &lt;pre&gt;<a name="line.148"></a>
<FONT color="green">149</FONT>     *   &amp;lt;indent &lt;strong&gt;xml:space=&amp;quot;preserve&amp;quot;&lt;/strong&gt;&amp;gt;    &amp;lt;/indent&amp;gt;<a name="line.149"></a>
<FONT color="green">150</FONT>     * &lt;/pre&gt;<a name="line.150"></a>
<FONT color="green">151</FONT>     * The value of the {@code indent} property will now contain the spaces.&lt;/p&gt;<a name="line.151"></a>
<FONT color="green">152</FONT>     *<a name="line.152"></a>
<FONT color="green">153</FONT>     * &lt;p&gt;{@code XMLConfiguration} implements the {@link FileConfiguration}<a name="line.153"></a>
